Patented Apr. 9, 1935 UNITEDl STATES PATENT OFFICE LOOM REED John JacobKaufmann,

Elkins Park, Pa., assignor Application December 1 11 Claims.

My invention relates to improvements in loom reeds, and more especiallyto a loom reed of the soldered type in which a novel mounting isprovided for the dents.

In the use of reeds of the conventional soldered type construction,difficulty is encountered because of the premature failure of the dents.The hard metal of the dents is in contact with the hard metal of thespring, and the strains 10 set up in this portion of the dent materiallyshorten the useful life of the reed. Vibrations may b e set up in thereed during use, which contribute to fatigue of the dent metal at ornear the place of contact.

One of the principal objects of my invention is to provide a loom reedconstruction which will have a long life and will withstand roughtreatment.

A further object of my invention is to provide a reed which will not beweakened by vibration of the dents.

Another object of my invention is to provide a loom reed which will belight in weight but at the same time durable and sturdy.

The nature and characteristic features of my invention will be morereadily understood from the following description, taken in connectionwith the accompanying drawing forming part hereof, in which:

Fig. 8 is a view in section taken on theline 8 8 of Fig. 7;

Fig. 11 is a fragmentary front elevation of a still further modied formof reed embodying my invention, the upper left hand portion being 5broken away to show the ends of the dents; and

Fig. 12 is a section taken on line I2 I2 of Fig. 11. l

It will, of course, be understood that the description and drawingherein contained are illustrative merely, and that various modificationsand changes may be made in the structure disclosed without departingfrom the spirit of my invention. y

Referring more particularly to the drawing, I5 designates one of theside bar members of the framework of the reed. A similar bar (not shown)may be used at the other side of the reed.

The dents I6 extend approximately the same length as the bars I5, andportions adjacent the ends of the dents I6 extend between respectiveconvolutions II of the spring coil I8. The thickness of the wire of thisspring coil of course determines the lateral spacing or gauge of thedents.

In order to maintain the dents in spaced relationship with their edgesin a common plane, strips I9 are employed. Each of the strips I9 has aface 20 conforming in shape to the internal portion of the coil I6 andone of these strips is interposed within the coil, at each side of thedents I6. Each of the strips I 9 has a. flat face 2| in contact with thedents I 6 and the side bar I5.

'Ihe dent ends 22 have spaces 23 therebetween, and these ends 22, thecoils I8 and the strips I9 are held in predetermined position by softmetallic material 24 which may be solder or the like and which coversand surrounds these several parts and fills the intersticestherebetween. 'I'he proper form and shape of the reed assembly is thusobtained and maintained.

In a reed of this character, as heretofore constructed, the strains inthe dents are concentrated at the place of contact or bearing of the endportions 22 of the hard metal dents on the hard metal coil I 8. 'I'hevibrations in the reed aggravate the condition already obtaining, andfatigue of the metal of the dent is brought about. The life of the reedis consequently shortened.

I have found, however, that by providing solder in the dent spaces, asat 25, filling the portions of said spaces adjacent the spring coils, animproved reed construction is obtained. This solder, in the preferredform of my invention is integral with the solder 24 and is extended forsome distance in the dent spaces toward the other end 55 of the dent andbeyond the place of contact of the dent ends 22 and the coil Il. I donot intend to limit myself, however to solder which is\inte gral, sincethe solder may be applied in any desired manner. A reed with myimprovement embodied therein overcomes the difficulties heretoforeencoimtered. By extending the solder in this manner, the effect of theconcentrated strains appears to be overcome. The solder seems to act inthe same manner as a bearing or resilient cushion. 'I'he weight is notmaterially increased, and the solder used as aforesaid does not renderthe reed dents excessively stifl'.A

In Figs. 3, 4, 'I and 8, I have shown my invention applied to a form ofreed with which a casing member 26 is employed on each side of the barand dents. This casing may be united to the end portion of the reed bysoft metal, such as solder. An external shape, as there shown, isrendered necessary by reason of the form of the reed slot in the lay' asfound in a number of looms. This casing member, as will be seen byreference to the drawing, may have a straight outer end portion 21,'anintermediate curved portion 28, and an inner straight portion 2|. Inapplying my invention to this form of reed, the solder 25 is preferablyextended and fills a portion of each dent space suillciently to bringthe solder some distance beyond the inner straight portion 29 of thecasing 26.

In Figs. 9 and l0 I have shown my invention applied to a. somewhatdifferent form of reed. Reeds of this type are intended for use withlooms in which the lay has a slotted receiving opening to which the endportion of the reed is complemental. It will be noted that in place ofthe casing shown in Figs. 3, 4, 7 and 8, the exterior of the end of thereed may be finished by securing thereto flat facing strips 3l having anouter plume surface. The solder 2l is extended for some distance beyondthe coil Il toward the other end of the reed and fills a portion of eachdent space adjoining each coil.

Figs. l1 and l2 show a still different form of y reed construction, inwhich two spring coils lla and lib are usedin place of the single coilfound in the other forms. These coils are spaced apart as shown at 3|.V'Ihe ends maybeflnishedby securing thereto flat facing strips 32, havingan outer plane surface, or the ends may be nlshed in any other desiredmanner to provide such a surface. 'I'he solder 25 is extended for somedistance'beyond the second coil IIb in a reed of this character and thusfills a portion of each dent space adjoining each coil IIb.

It will therefore be seen that I have provided a novel reed constructionwhich will overcome the objections heretofore encountered.`
